Convenience sampling is a common method of sample collection where the samples are drawn because they are easy to obtain. For example, a store owner wants feedback about the products that are sold. One of the easiest ways to do so is by asking questions to the customers who just happen to be in his store. Surveys conducted on social media, shopping malls, or randomly on campus are a few more examples of convenience sampling. This approach is often advantageous—samples are easy to obtain, the method is cost-effective, and it consumes less time. This method can be used to carry out a pilot study or to generate a hypothesis. However, samples drawn by this method are highly biased, do not accurately represent the population, and all factors that might influence the subjects' responses are not considered.
